Customer Questions and Answers for Cold Control (Refrigerator Thermostat) by Whirlpool

This cold control thermostat regulates your refrigerator's temperature by cycling cooling on and off based on air temperature at the sensing bulb. Replacing a worn control restores accurate settings and consistent cooling performance. What it does:

• Monitors compartment temperature via a capillary sensing bulb
• Opens/closes electrical contacts to start and stop the compressor (and related cooling circuits)
• Helps maintain the temperature you set on the control dial
• Failure symptoms include: unit too warm or too cold, runs continuously, won't start until the knob is moved/tapped, or erratic temperature swings

• 1 thermostat

• Disconnect power before servicing; wear cut-resistant gloves
• Note wire positions or take a photo; transfer the dial/shaft and any mounting hardware from the old control if reused
• Route the capillary bulb exactly as original; do not kink, pinch, or cut it; secure with existing clips
• After install, set to a mid setting and allow up to 24 hours for temperatures to stabilize
